CAN, LIN, FlexRay, and CAN-FD Serial Buses

Keysight Technologies, Inc. oscilloscope automotive options help electronic system designers test and debug the physical layer of automotive serial buses faster. CAN, LIN, FlexRay, and CAN-FD serial buses are the backbone for communication among many separate controllers, sensors, actuators, and ECUs located throughout automotive and industrial designs. These serial bus interfaces provide content rich points for debug and test. However, since these protocols transfer bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1s and 0s to protocol requires significant effort, cannot be done in real-time, and includes potential for human error. Also, traditional oscilloscope triggers are not sufficient for specifying protocol-level conditions.

Extend your oscilloscope capability with Keysight’s N8803C CAN, LIN, FlexRay, and CAN-FD protocol triggering and decode application. This software makes it easy to debug and test designs that include these buses using your Infiniium oscilloscope.

– Set up your oscilloscope to show CAN(FD), LIN, or FlexRay protocol decode in less than 30 seconds

– Get access to a rich set of integrated protocol-level software triggers – Save time and eliminate errors by viewing packets at the protocol level – Use time-correlated views to quickly troubleshoot serial protocol problems back to their

timing or signal integrity root cause – With the CAN-dbc symbolic trigger and decode capability, engineers can now test the

physical layer of this differential bus at a higher abstraction level

30 second CAN(FD), LIN, or FlexRay setup

Configure your oscilloscope to display protocol decode in under 30 seconds. Use Auto Setup to automatically configure sample rate, memory depth, threshold, trigger levels, and clock recovery for FlexRay.

Support for both analog and digital channels

Acquire serial buses using any combination of scope or digital channels. Using digital channels on MSO models preserves analog channels for viewing other time-correlated signals.

CAN(FD), LIN, and FlexRay Setup and Protocol Triggering

Get access to a rich set of integrated software protocol-level triggers. The application includes a suite of configurable protocol-level trigger conditions specific to CAN, LIN, FlexRay, and CAN-FD. When serial triggering is selected, the application uses software-based triggering or hardware-based serial triggering . With protocol triggering, the oscilloscope takes signals acquired using either a scope or digital channels and reconstructs protocol frames after each acquisition. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.

CAN-FD trigger

Quickly set up trigger for a unique frame or error condition.

Specify the CAN signal type

Use single-ended probes or differential probes.

LIN trigger

For triggering on LIN packets, choose a combination of ID, parity, and payload values.

FlexRay trigger

Quickly specify frame ID and repetition factor (optional) for triggering and searching.

1. Infiniium S-Series supports CAN, LIN, and CAN-FD hardware-based serial trigger, not FlexRay. Infiniium 9000-Series supports CAN, LIN as hardware-based serial trigger, not FlexRay and CAN-FD.

CAN and CAN FD Protocol Decode

Quickly move between physical and CAN-FD protocol layer information using the time-correlated tracing marker. Display protocol content using embedded decode in the waveform area or, see protocol events in a compact listing format. Along with CAN interface innovation, CAN-FD will replace legacy CAN bus line. With N8803C protocol decoder, up to 10 Mbps CAN-FD signals also can be decoded with time-correlated tracking marker.

Import industry-standard .dbc files for symbolic triggering and decode. Message and signal values are displayed on the listing and in the waveform in symbolic format, making it easier to understand the oscilloscope capture.

Long time captures using segmented memory

In this example, CAN traffic was captured for near 42 seconds. Segmented memory uses time tags to track time between segment acquisitions.

CAN-FD (Flexible Data-rate) Protocol Decode

CAN-FD protocol decode supports the new CAN (ISO 11898-1) specification, so that it will decode up to 10 Mbps FD data rate, while supporting standard CAN data rate for control part. FD data rate support from 1 Mbps and Infiniium S-Series supports hardware-based serial triggering on CAN-FD signals so you can get the packet you want to see. This trigger supports frame, and bit-specific options such as BRS, CRC ESI, and errors.

FlexRay and LIN Protocol Decode

Quickly move between FlexRay physical and protocol layer information using the time-correlated tracing marker. Display protocol content using embedded decode in the waveform area, or see protocol events in a compact listing format. Minor tick marks indicate clock transitions. Major tick marks indicate segments of the serial packets.

LIN decode embedded in waveform area

Use the oscilloscope waveform area to display decode information.
